SPECIFICATION forming part of Letters Patent No. 427,772, dated May 13,1890.

Application filed November 12, 1889. Serial No. 330,088. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN T. LEE, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented new and useful Cutting-Forceps, of which thefollowing is a specification.

The object of this inventionis to provide a pair of cutting-forceps forcutting the incisors of horses, and to accomplish the same in such amanner as to make a clean out and avoid breaking the enamel adjacent tothe cut, and, furthermore, to provide a pair of forceps so constructedas to be simple and cheap and to lend the greatest amount of leveragefor operating the cutting-bar.

\Vith these general objects in view the in vention consists in certainfeatures of construction hereinafter specified, and particularly pointedout in the claim.

Referring to the drawings, Figure l is a perspective of a pair offorceps constructed in accordance with my invention. tail inlongitudinal section of the upper end of the same. Fig. 3 is a detail ofthe bar-operating lever. Figs. 4 and 5 are details in perspective ofmodifications.

Like numerals of reference indicate like parts in all the figures of thedrawings.

In practicing my invention I provide two sections or members 1 and 2,the former being designated as a movable or hinged section and thelatter as the stationary section. The stationary section 2 comprises arear handle portion 3, which terminates in a perforated shoulder 4t, andbeyond the same there is formed a head 5, the extremity of which iscurved to form a jaw 6, terminating in a cutting-head 7. Between theshoulder 4 and the jaw there is secured to or formed upon the section astrap or guide 8, forming a passage in. which is mounted the cutter-bar9, the upper end of which is in line with the cutter 7 and is beveled toform a cutting-edge 10. The lower end of the cutting-bar is slightlyreduced, forming opposite shoulders 11, and below the shoulders and atthe lower end of the ,bar is formed an offset lug or projection 12,

perforated as at 18. The section 1, which is the pivoted or hingedsection, also terminates Fig. 2 is a dein handles 3 at one end, and atits upper end is provided with a concaved opening or recess 18 for thereception of the perforated shoulder or lug 4 upon the opposite section.Projecting at a right angle from the upper end of the section 1 and ateach side thereof is a strap or arm 14, perforated as at 15 and 16.Through the perforation 15 and the perforation in the shoulder or lugethere is inserted a pin 17, by which the section 1 is pivotallyconnected to the section 2. Through the opening 16 and the opening inthe lug 12 there is inserted a second pin 18, which pivotally connectsthe forward ends of the straps with the lower end of the cutter-bar.

The cutting-edges of both the jaw and the cutter-bar are preferablyslightly concave, as shown, for the purpose of adapting the twoconjointly to the natural contour of the illcisor. If desired, and asshown in Fi 4, the cutting-edges may be disposed at a right a11- gle tothat shown in Fig. 1, and, as also shown by the modification, Fig. 5,said edges may be serrated in order to increase the cutting efficiencyof the same.

The operation of my invention will be readily understood by thoseconversant with the treatment of horses, in that it is simply necessaryto spread the handles and introduce the cutters over the incisor andthen lower the pivoted handle.

Having thus described my invention, I claim- In an instrument of theclass described, the combination, with the section 2, terminating at oneend in a handle 3 and at its opposite end in a curved head 5, theextremity of which is beveled to form a fixed cutter below the head andupon the opposite side provided with an outwardly projecting perforatedcurved bearing shoulder 4 and at its front face with a fixed guide 8, ofthe sliding cutter 9, mounted in the guide beveled at its upper end, asat 10, and having its lower end terminating in the shoulder 12, forminga stop for the upward movement of the cutter by coming in contact withthe lower end of the guide and perforated, as at 13, and the section 1,terminating at one end in the handle 3 and at the upper end providedwith the curved recess 13, to bear upon the shoulder 4, and In testimonythat I claim the foregoing as the opposite straps 14, having their rearends my own I have hereto affixed my signature 1o rigid with the sectionand forming end walls in presence of two witnesses.

for the recess, and having their forward ends pivoted, as at 18, to theperforated shoulder JOHN 12 of the movable cutter 9, and the pivot 17',Witnesses:
